Seed Vigour Tests on seven Cultivars of Phaseolus vulgaris Grown in Chamoli District of Uttarakhand, India

Abstract

Rajmash (Phaseolus vulgaris L. family; fabaceae) is also known as kidney bean/ French bean. It is an annual plant and cultivated throughout the world for their edible beans. The present study was conducted to investigate the effect of seed vigour by germination test of different cultivars of Phaseolus vulgaris grown in Chamoli district of Uttarakhand. The experimental material constituted a collection of 7 cultivars (Red small, Red big, Grey, Pink, Yellow, Brown, White) of Phaseolus vulgaris. The seed samples of seven cultivars of Phaseolus vulgaris were taken from Joshimath, District Chamoli Garhwal Uttarakhand. Morphological aspects viz; seed weight, seed moisture content, seed density and seed diameter were recorded prior to germination test of Phaseolus vulgaris at Seed Testing Laboratory, Department of Seed Science and Technology, H.N.B Garhwal University. Seeds were sterilized with 0.2% sodium hypochlorite solution for germination test. Two replicates of each variety and 25 seeds in each replicates were kept in petriplates on whatman filter paper. Petriplates were kept in seed germinator at 25 ± 2 °C until final count. The number of normal seedling was counted at the final count, higher the number of normal seedlings greater is the seed vigour. The germination percentage was found 100% in five cultivars, and the other two cultivars showed 96.66% in yellow seeds and 68.33% in Grey cultivar of Phaseolus vulgaris. Brown cultivars represented maximum dry weight of root (0.029 g) while minimum dry weight of root has been recorded in yellow cultivar (0.01353 g). Maximum vigour index were recorded in brown cultivar and minimum was recorded in pink cultivar. The findings from the study indicate that brown cultivar of Phaseolus vulgaris is highly vigours.
